File Attributes

The system stores information about files in a structure known as an inode. This information includes:

• The file's type (regular file, directory, symbolic link),
• The file's size (in bytes),
• ctime, the time the file's inode was last modified,
• mtime, the time the file's content was last modified,
• atime, the time the file was last accessed (read, executed),

and file permissions:

• The file's owner (UID),
• The file's group (GID),
• The file's mode bits or permissions bits.
